发动机工作过程计算VB源代码包括汽油机和柴油机

自己编写的VB程序，请大家多指教！（赚一点积分嘿嘿……） 部分代码如下： Private Sub Command1_Click() k = 1.4 D = Val(Text1.Text) S = Val(Text2.Text) Ne = Val(Text3.Text) nh = Val(Text4.Text) ε = Val(Text5.Text) L = Val(Text6.Text) R = Val(Text7.Text) ge = Val(Text8.Text) P0 = Val(Text13.Text) T0 = Val(Text12.Text) gc = Val(Text9.Text) gh = Val(Text10.Text) go = Val(Text11.Text) mt = Val(Text14.Text) i = Val(Text15.Text) ι = Val(Text16.Text) α = Val(Text38.Text) ξz = Val(Text40.Text) φi = Val(Text41.Text) ηm = Val(Text42.Text) n = Val(Text45.Text) Vh = (S * 0.01) * 3.14 * (D * 0.01) ^ 2 / 4 '排气过程 Pr = 1 + 0.3 * n / nh Tr = 850 + 350 * n / nh Text17.Text = Val(Pr) Text18.Text = Val(Tr) '进气过程 δ = 0.5 ΔT = ΔTh * (110 - 0.0125 * n) / (110 - 0.0125 * nh) Pa = Int(10 ^ 3 * (P0 * (1 - ((10 * n ^ 2 / 520 / 10 ^ 6) / 10.6 ^ 2 / 0.75 ^ 2) * (ε - δ) ^ 2 / (ε - 1) ^ 2) ^ (k / (k - 1)))) / 10 ^ 3 γ = Int(10 ^ 3 * (T0 + ΔT) * Pr / Tr / (ε * Pa - Pr)) / 10 ^ 3 Text44.Text = γ Text19.Text = Pa Ta = (T0 + ΔT + γ * Tr) / (1 + γ) ηv = ε * Pa * T0 / (ε - 1) / P0 / Ta / (1 + γ) Text20.Text = Val(Int(1000 * Ta) / 1000) Text21.Text = Val(Int(1000 * ηv) / 1000) ' 压缩过程 n1 = 1.46 - 0.05 * Nn / n Pc = Pa * ε ^ n1 Tc = Ta * ε ^ (n1 - 1) Text22.Text = Val(Int(1000 * Pc) / 1000) Text23.Text = Val(Int(1000 * Tc) / 1000) '燃烧过程 L0 = (gc / 12 + gh / 4 - go / 32) / 0.21 M1 = α * L0 + 1 / mt Cv1 = (4.815 + 0.415 * 10 ^ (-3) * Tc) * 4.1868 M2 = 0.79 * α * L0 + gh / 2 + gc / 12 A = (3.7 + 3.3 * α) * 10 ^ (-4) * 4.1868 B = (4.4 + 0.62 * α) * 4.1868 μ0 = M2 / M1 μ = (μ0 + γ)
